Bounce Lighting
When taking a picture of a baby or small children,
do not shoot the flash straight on to them. Bounce
the light off the ceiling or wall so that it won’t scare
them. The lighting on a subject in front of the wall,
creates an unnecessary sharp shadow on the wall
resulting the picture disappointed. Bounce the light
off the ceiling or wall to soften the light on the
subject, and the shadow fade out.
Turn the flash head upwards. It turns upward
to 45 > 60 > 75 > 90 degrees.
When the flash head stays at turning or tilting
position, the zoom setting position of Di466 is
automatically set at the position for 25
mm(50mm / film camera standard) focal
The wall or ceiling in this case should be flat
surface and white color is preferable. Colored
ceiling or wall may reflect its color on the
subject.
AF assist light emitter
Under the low light condition, in the dark place, AF assist light will automatically
emit the beam and illuminate the subject, so that the camera can easily
focus the subject in darkness. The beam is however not shown in the picture.
*Remark: Some camera models are originally programmed to disable the AF assist
light function.
For Panasonic only
Following functions are available on Panasonic cameras. Refer to camera
owner's manual for details.
Slow synchronization
When taking pictures against a dark background
landscape, this feature will slow the shutter speed when
the flash is activated. Dark background landscape will
appear brighter.

2nd curtain flash fires just before the shutter closes.
Changing the flash timing can create interesting effects
in your picture. The slower the shutter speed, the better
the effects turn out.

flash exposure instead of automatic controlled exposure. You can set
Di466 Four Thirds for non-automatic flash mode, and select the desired

Following functions are available on Olmypus cameras. Refer to camera
owner's manual for details.
Slow synchronization
The flash is controlled at a slow shutter speed to the correct
exposure for both the main subject and back ground in low
light conditions or at night.
Red-eye reduction flash
In the red-eye reduction flash mode, a series of pre-flashes
are emitted just before the regular flash fires. This helps
accustom the subject’s eyes to the bright light and minizes
the red-eye phenomenon.
Slow synchronization (2nd curtain)
2nd curtain flash fires just before the shutter closes.
Changing the flash timing can create interesting effects in
your picture. The slower the shutter speed, the better the
effects turn out.
**
for M and S mode ONLY
Slow synchronization / Red-eye reduction
While using slow synchronization with flash shooting, you
can also use this funtion to achieve red-eye reduction.
When shooting a subject against a night scene, this
function allows you to reduce the red-eye phenomenon. As
the time from emitting pre-flashes to shooting is long in
2nd curtain synchronization, it is difficult to achieve red-eye
reduction. Hence, only 1st curtain synchronization setting
is available.
Wireless Remote Flash
Di466 Four Thirds has a wireless remote flash system as a slave unit.
You can enjoy creative flash photography with multiple lightings from the
various directions. 2 slave modes are provided, Slave 1 (S1: color green)
for digital pre-flash system and Slave 2 (S2: color blue) for analog flash
system.

system. The master flash is to be set at TTL mode.
